#4 Filter() default argument $type

[Querubain]

Function filter takes two arguments:

function filter($raw, $type)...

But it's called without the second argument from several pieces of code like:

content=filter( $raw ) . $content;

A solution can be put a default at function definition:

function filter($raw, $type = "wiki")...

Thanks Querubain, its a good solution that I already applied.
